Java解释XML文件的小例子

<?xml version="1.0" encoding="GBK"?>

</addresslist>

上面是test.xml文件, 下面是DOMDemo.java文件

package org.lxh.xml.dom;

import java.io.File;
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;

public class DOMDemo {
  public static void main(String[] args){
    //1. build DocumentBuilderFactory
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    
    //2. 
    DocumentBuilder builder = null;
    try{
      builder = factory.newDocumentBuilder();
    }catch(ParserConfigurationException e){
      e.printStackTrace();
    }
    
    //3.
    Document doc = null;
    try{
      doc = builder.parse("D:" + File.separator + "test.xml");
    }catch(SAXException e){
      e.printStackTrace();
    }catch(IOException e){
      e.printStackTrace();
    }
    
    //4.
    NodeList nl = doc.getElementsByTagName("name");
    
    //5.
    System.out.println("姓名: " + nl.item(0).getFirstChild().getNodeValue());
    
  }

}
